In this research we examined if it might be possible that a client accomplishes an ad-hoc analysis of an existing building with the intention of prospective revitalization. The aim is to give a client who incidentally faces a building the possibility to run an in situ usability simulation. To accomplish this we recommend Location Based Services that can be accessed by common remote sensing devices. These devices should automatically connect to server-based applications, which compare the requirements of the client with the existing building and run remote simulations on concrete further utilization. The newly generated information will then be passed back to the clients’ device. In the paper we address a scenario of a prospective client who visits a city where he hits on an unused building he might be interest in. The client wishes to gain immediate and accurate information if the building is able to meet his demands regarding the space needed for his company. Different techniques investigated, their assets and drawbacks will be described that could accomplish suchlike tasks.
